How many times less is 102 than 106? Express your answer as an integer power of 10. (1 point)

0.0001

10^4

10^−4

10,000
To find out how many times less 102 is than 106, we divide 106 by 102:

106 ÷ 102 = 1.0392

So, 102 is approximately 1.0392 times less than 106.

Expressed as an integer power of 10, this can be written as 10^0, because it is approximately 1 times less.

Two weeks before an examination day, a librarian monitored the number of students who visited the library. Then they compared it with the number of visits made in an average week. Approximately 2×10^3 visits were reflected in their logbook during this two-week period, while only about 5×10^2 were reflected on an average week. How many times higher is the number of library visits before examination day compared to the library visits in an average week? Your answer should be a whole number. (1 point)
To determine how many times higher the number of library visits before the examination day is compared to an average week, we need to divide the number of visits before the examination day by the number of visits in an average week.

Number of visits before examination day: 2×10^3

Number of visits in an average week: 5×10^2

To divide these quantities, we divide the coefficients (2 by 5) and subtract the exponents (10^3 divided by 10^2):

(2×10^3) ÷ (5×10^2) = 2/5 × 10^(3-2) = 2/5 × 10^1 = 2×10^1 = 20

Therefore, the number of library visits before the examination day is 20 times higher compared to the number of visits in an average week.
Why do you keep getting wrong answers?
Apologies for the repeated mistakes. Let's reevaluate the problem and find the correct answer.

Number of visits before examination day: 2×10^3
Number of visits in an average week: 5×10^2

To find how many times higher the number of visits before the examination day is compared to the number of visits in an average week, we divide the number of visits before the examination day by the number of visits in an average week.

(2×10^3) ÷ (5×10^2) = (2/5) × (10^3 / 10^2) = 0.4 × 10^(3-2) = 0.4 × 10^1 = 4

Therefore, the correct answer is that the number of library visits before the examination day is 4 times higher compared to the number of visits in an average week.
THANK YOU!
You're welcome! Apologies again for the earlier mistakes, and thank you for your understanding. If you have any more questions, feel free to ask.
It takes 10 years for a $100 monthly bank deposit to amount to $15,528.23 when invested at 5% interest compounded monthly. Round to the nearest place value, then express the amount $15,528.23 in the form of a×10^n where a is single digit. (1 point)

In three to four sentences, explain how climate change could impact the formation of hurricanes.
Climate change can impact the formation of hurricanes in several ways. Warmer ocean temperatures can provide the necessary fuel for hurricanes to form and intensify. Climate change also alters atmospheric conditions, such as wind patterns or moisture content, that can influence hurricane formation. Rising sea levels due to melting ice caps and thermal expansion can lead to increased storm surge and coastal flooding during hurricanes. Overall, climate change has the potential to increase the frequency, intensity, and impact of hurricanes.
In 3–5 sentences, explain how meteorologists use weather data to predict the probability of a catastrophic wildfire.
Meteorologists use weather data to predict the probability of a catastrophic wildfire by examining various factors. They analyze temperature, humidity, and wind patterns to assess conditions that favor rapid fire spread. High temperatures and low humidity increase the dryness of vegetation, making it more susceptible to ignition. Wind direction and speed play a crucial role, as stronger winds can rapidly spread wildfires. Additionally, meteorologists monitor drought conditions and precipitation patterns to understand overall fuel moisture levels. By combining these data, meteorologists can provide valuable insight into the potential for catastrophic wildfires.
